Melisende of Jerusalem vs Wang Zhen

Upon the death of her father Baldwin II, Melisende was crowned Queen of Jerusalem alongside her husband Fulk V of Anjou. This joint rule was intended to secure the succession but led to conflict as Fulk sought to exclude Melisende from power.

Fulk accused Melisende of adultery with Hugh II of Le Puiset, leading to a rebellion by Hugh's supporters. The crisis was resolved through the intervention of the Patriarch, and Melisende's position was strengthened, leading to her becoming sole ruler after Fulk's death.

After Fulk's death in a hunting accident, Melisende became sole regent for her son Baldwin III. She effectively ruled the Kingdom of Jerusalem for over a decade, managing its defenses and diplomacy during a period of external threats.

Melisende commissioned the renovation and expansion of the Church of the Holy Sepulchre in Jerusalem, including the addition of a new choir and crusader-style decoration. This project enhanced the religious prestige of the kingdom and demonstrated her piety.

Baldwin III, now of age, demanded sole rule. Melisende refused, leading to a brief civil war. Baldwin besieged her in the Tower of David, forcing her to surrender. She was granted the city of Nablus as a fief but lost political control of the kingdom.

Wang Zhen became the chief eunuch of the Directorate of Ceremonial, gaining the trust of the young Zhengtong Emperor. He used his position to dominate the court, sidelining scholar-officials and accumulating immense personal power.

Wang Zhen orchestrated the purge of several high-ranking officials who opposed his influence, including the Grand Secretary Yang Shiqi's faction. He replaced them with loyalists, weakening the civil service and concentrating power in the eunuch bureaucracy.

During the Battle of Tumu Fortress, Wang Zhen was killed by his own officers who blamed him for the impending disaster. His death did not prevent the emperor's capture, and he was posthumously blamed for the crisis.

Wang Zhen persuaded the Zhengtong Emperor to personally lead a military campaign against the Oirat Mongols, despite opposition from experienced generals. His arrogance and lack of military planning led to the disastrous Tumu Crisis.

After the Tumu Crisis, the new Jingtai Emperor posthumously stripped Wang Zhen of all titles and confiscated his property. His family was executed, and he was vilified in official histories as a corrupt eunuch who caused the dynasty's near-collapse.
